To all whom t may concern.'

Be it known that I, WILLIAM C. ENGEL, a citizen of the United States, and resident of Ashland, in the county of Schuylkill and State of Pennsylvania, have'inve'nted a new and Improved Automobile Spring Regulator, of whichthe following is a full, clear, and exact description.

My invention relates to a spring regulator, and more particularly aims to provide a de-.

ing to the movement of the axles and the chassis, have responded to this reaction 1ntoo violent a manner.

With thisin mind numerous devices have been placed upon the market with a view of overcoming this diiculty, but for the most part these members have been relatively manufacture.

Thus my present lnvention alms to provide a spring regulator particularly adapted for use in connection with the suspension' -of automobiles, and by means of which the action of the springs will be cushioned, or` regulated to such an extent as to overcomethe diculties aforementioned in this connection. v v. t

Still another object of this invention is the .constructionv of a device of- .the character stated which shall embody extremely simple mechanism, and shall thus be capable of lieing manufactured at a nominal figure.

Still further objects of this invention will become apparent in the annexed specifica- Vtion taken in connection with the drawings, which latter illustrate one practical embodiment thereof, and in which:

v Fi ure 1 is a side elevation of my regulating evice, and showing the same associated with the conventional chassis and axle of a vehicle.

Figure 2 is an enlarged sectional side view of the same, and

Figure 3 is a transverse sectional View taken along the line 3 3 andv in the direction of the arrows indicated in Figure 1.

Referring now more particularly to Figure 1 it will be seen that the reference nuthe axle to gradua ly meral 5 indicates a frame supported upon an axle 6 by means of any suitable type of spring 7, t e foregoing'being all conventional construction, and forming no-part of my invention. v

lt will also beseen in the embodiment illustrated, that l have shown my improved type of spring regulator as interposed be- .tween the axle 6 and the frame 5.

Referring now more particularly to the detailed construction of this regulator, it will be seen that'the same includes a pair of sections 8 and 9 which are preferably cylindrical, and of such a size that they may be telescopically disposed with 'respect to each other. Also in the embodiment illustrated the section 9, is shown with an open' ing 10, and this opening constitutes a valve vport the flow of fluid through the same being controlled by any suitable type of valve, such as a flap 11, the movement of which may be limited by'a member 12.

Now assuming that the sections 8 and 9 are associated with the frame and axle respectively, it will be understood that when the axle moves away from the frame that the valve 11 will move to the position incli- 'cated in dott/ed lines in Figure 2, thus permitting air to flow freely into the interior of the sections. However, upon the axle rebounding towards thev frame 5, the air will be compressed within the sections 8 and. 9, and thusthe' entire device will serve to regulate this rebounding action, it bein noted, however, that an opening 13 is pre erably providedin the body of the valve, which o ning serves topermit ofv a slow' escape ogthiscom ressed air, to thus allow assume its normal positm. h '1 ow wit 4a view o roper y retainin the regulator in this pdsition, it will h noted that l preferably associate spherical, elements 14, one with each of the sections 8 and 9, and these spherical elements are adapted to co-operate with socket members 15 allixed to the frame and axle respectively, thus providing ball and wcket joints at these point-s. Ubviously by this construetion, the normal movement of the axle with respect to the frame is not interfered with in the slightest in View of the fact that this mounting is what might; be termed universal, Htdwever, it will be obvious that my re la-tor will at all times serve to accompllsh the result 4or which it is intended, it

I being understood that the same is capable v of being placed in an desired position, and

' that the structure o this element may be varied in many particulars.

It Will further be understood that numerous modifications of structure might readily be resorted to without in the least departing from the scope of my claims, which arel. rlhe combination with the chassis, axle and spring of a vehicle, of two cylinders; each having an open end and telescoping one in the other, one of the cylinders having v an opening in its closed end, a ilapI valve on
